Abstract
Gas chromatography (GC) with a Flame Ionization Detector (FID) has been widely used for the analysis of volatile organic compounds in various fields. Instrument portability and miniaturization of the FID for micro GC (μGC) applications are of increasing interest. This thesis describes the design and characterization of a planar on-chip counter current micro FID (μ-FID). The μ-FID fabricated in both quartz and Titanium (Ti) substrates were characterized and the Ti μ-FID showed great improvements in detection limit and sensitivity over other prototypes. This Ti μ-FID design is further integrated with a Ti separation column to fabricate a planar μGC-FID Ti tile for the first time. This Ti μGC-FID tile is explored for its detector performance attributes and some routine GC applications are examined. This novel Ti μGC-FID tile, with an on-chip single monolithic design, is found to provide a very low detection limit (9 pgC/s) and a high sensitivity (60 mC/gC).
